#include <nitro/ctrdg.h>u16 CTRDG_EraseAgbFlashSector(u16 sec_num);
Corresponding AGB function: u16 (*EraseFlashSector)(u16 secNo)
| sec_num | Target flash sector number |
Returns 0 if the erasure succeeds. Returns a non-zero value if it fails.
Erases the data within the specified target sector number.
Normally, this routine does not need to be called before writing because it is called inside the writing routine.
This function returns an error if the target sector number is out of range.
The access cycle setting does not need to be set beforehand because it is created inside the function.
In addition, the OS_InitTick function must be called before this function because clock ticks are used by this function to measure timeouts.
Note: All interrupts are disabled inside this function and the catridge bus is locked for a set period.
In particular, do not use DMA for automatic startup during direct sound and V/H blank synchronization, display synchronization, or cartridge request.
In addition, the AGB backup device cannot be accessed normally by the IS-NITRO-DEBUGGER.
However, be sure to check operations using an actual DS handheld unit since normal access is possible with actual DS units.
(This will be fixed in a future version of IS-NITRO-DEBUGGER.)
